BOOK-CUTTING MACHINE.

$PEC1EICATION forming part of Letters Patent No. 336,304, dated February 16, 1886.

Application filed July 24, 1885.

To all whom it may concern.-

Be it known that 1, WILLIAM F. ELLIS, a citizen of the United States, residing at New York, county and State of New York, have invented certain new and useful Improvements in Book-Cutting Machines, of which the following is a specification.

This invention embraces certain improve ments in that class of book-cutting machines in which the books are clamped to a bed constructed to be moved in an inclined direction against a stationary knife having its face vertical and its cutting-edge horizontal, and has for its object to make such machines automatic in action, and to generally improve their construction, as will be fully set forth, reference being had to the accompanying drawings, in which- Figure 1, Sheet 1, is a plan view of my improved automatic book-cutting machine. Fig. 2, Sheet 1, is a vertical transverse section on the line w :0, Fig. 4. Fig. 3, Sheet 2, is an end View. Fig. 4, Sheet 2, is a longitudinal section on the line y 3 Figs. 1 and 3. Fig. 5, Sheet 1, is a vertical section of the traveling bed, taken on the line 2 2, Fig. 1. Fig. 6, Sheet 1, is a horizontal section of the same, taken on the line z a, Fig. 5.

The main frame comprises the side pieces, aa, theinclinedguide-pieces a", and the trans verse connecting-girders a a The upper surfaces of the inclined guide-piece a and the top side piece, a, are in one plane, and on them is fitted to slide the traveling bed I), which carries the horizontal cutting-table c, on which the pile or piles of books d is or are clamped in the ordinary manner. The parts of the bed I), which bearon theinclined guides of the frame, are provided with oil-chambers b b, in which a lubricant with a suitable packing is placed. The knife 6 is attached to the upper part of the side piece, a, with its face vertical and its edge in a horizontal position,

by being secured by screws or bolts to the face of the knife 6, so that its cutting-edge Serial No. 172,531. m. model.)

shall have the proper clearance, and its horizontal adjustment is accomplished by manipulating the bolts or set-screws e* e", which pass through flanges on the side piece, a, and butt against the top of the knife-holder e.

The edges of the pile or piles of books are trimmed by causing the traveling bed I) to move up in the inclined guides of the main frame by a system of gearing, comprising the rack f, secured to the under side of the bed b, the gear-wheel f on the shalt f, meshing therein, the pinion g, the wheel 9 on the shaft g, and the pinion h, fitted to run loosely on the driving-shaft h, on which shaft is secured the driving-pulley h".

When the bed 1) reaches its highest position,- the This pinion ,h is pro- Vided with clutch-teeth, shaped to fit into the clutch lf'is thrown out of gear with the pinion from the bed I) is an arm, j which, by striking the blockj when the bed reaches its upper position, moves the bar 2', and, through the bell-crank lever t and clutch-bar i, throws the clutch it out of gear, thus allowing the bed b to I.

fall, the driving-shaft continually rotating in one direction, as indicated by the arrow on the pulley h". In the block j is pivoted the latch which, when placed in upward position, as shown in Figs. 1 and 2, is struck by the v arm j" when the bed I) descends, thereby imparting an opposite movement to the bar t', and throwingthe clutch h in gear with the pinion h, thus causingthe bed to again ascend. This up-and-down movement of the bed continues as long as the latch j is in the position above indicated, and when it is desired to have the bed stop in its lower position, for the purpose of clamping another batch of books thereon, which is generally after four full movements have been made, the latch is thrown down,"

' grippers k pivoted in jaws on the blocksk and I0 and provided with handles, by which they may be readily operated in adjusting the blocks in the desired positions, the grippers 10 being so shaped that they look the blocks more rigidly on the rod k as the pressure applied to the blocks increases. These blocks It and 7c" are provided at their opposed faces with cushioning-springs If, against which strikes the arm I), attached to the bed I), the upper spring it having for its function, principally, to start the bed downward after the wooden cuttingblocks placed under the piles of books d has come in contact with the knife 6.

The next, and perhaps most important, feature of the invention is the method of automatically moving the pile of books away from the knife after a out has been made, and rotating it so as to present another side of the books to the knife to be acted upon during the succeeding upward movement of the bed I). This is accomplished by fitting a frame, Z, on the top of the bed b, to slide transversely thereon, and fitting in this frame I the rotating table a, on which the piles of books dare directly clamped, in the usual manner,'by the hand-wheel and clamping device 0. On the under side of the table 0 is an annular bearing, 1%, fitted into an opening in the top of the frame Z, and on the lower end of this bearing are formed the ratchet teeth m, into which meshes the ratchet-rack n, adjustably secured to the bar a, pivoted to the sliding bed b, and held against the teeth m by means of the springs 11*. In square bearings in the frame 1 is held the locking-bar 0, provided with two projecting lugs, 0 0, adapted to catch in two diametrically-opposite open ings of four equidistant openings formed in the annular bearing an on the table 0, said locking-bare being moved and held forward, so as to retain the table at in any of its four positions, by the spring 10, and the set-screw q, secured in the frame 1, determines the backward limit of the bar 0. On the under side of the bar 0 are formed the rack-teeth 0 into which meshes the pinion r, secured toa shaft rotating in a bearing on the bed b, and to the other end of this shaft is fixed the bevel-wheel 1', having inclined teeth, which mesh into the inclined teeth of the rack s. This rack s is fitted to slide in vertical guides on the inside of the side frame, a, and is connected to one end of the lever t, pivoted at t to'the side frame, a, the other end,t",of this lever t'being formed as shown, so'that its upper side is and releases the table 0.

parallel with the guides on the main frame, upon which the bed 1) slides, when the rack 19 is in its upward position, and this device is actuated by the weighted latch it, pivoted to the bed I). 1

The operation of this part of the machine is as follows: As thebed b moves up on the main frame, carrying the pile of books d against the knife e, the weighted latch it comes in contact with the end i of the lever t, and leaves the lever t and rack s in the position shown in Fig. 4, said rack being held down by the spring 8, and the bevel-wheel r moves over the top of the rack' without coming in contact therewith. Now,as soon as the out is finished and the bed I) commences to fall down, the latch to comes in contact with the part 6 of the lever 25, and pushes this end of it down, thus raising the rack s, so that it meshes with the bevel-wheel r, causing said wheel 0'' and pinion rip rotate until the latch u leaves the lever t, allowing the spring s to pull the rack down away from the bevel-wheel r. By this rotation of the pinion r the locking-bar 0 is first drawn back The frame Z is then moved away from the knife e by the lockingbar 0 coming in contact with the set-screw q, and the table 0 is rotated one-quarter of a revolution by the ratchet-teeth on the table working in the teeth of the ratchet-rack 'n. the bed b reaches its lower position the rack 8 leaves the bevel-wheel r, and the locking-bar is moved forward by its spring 10, and firmly locks the table with another side of the books Before presented to the knife 6, the sliding frame Z with its attached parts being then moved forward by means of the spring v,placed between a lug on the sliding frame [and a collar on the bar 12, which bar is secured to the bed I).

slide over the teeth of the ratchet-rack n. This forward movement of the frame Z and piles of books 01 is arrested by a block, d, of wood on the top of the books coming against the face of the knife. tutes the pattern, and is of the exact size of the pile of books when trimmed.

Having now described my invention, whatI claim, and desire to secure by Letters Patent,
